• What is the cause and solution for SAP error message IPPECIF155 - RFC connection to logical system does not exist ?

  The SAP error message IPPECIF155 indicates that there is an issue with the RFC (Remote Function Call) connection to a logical system that does not exist or is not properly configured. This error typically arises in scenarios involving integration between different SAP systems or when trying to access data from a logical system that has not been defined in the system.
  Cause:
  
  Missing Logical System Configuration: The logical system you are trying to connect to has not been defined in the SAP system.
  Incorrect RFC Destination: The RFC destination may be incorrectly configured or pointing to a non-existent logical system.
  Transport Layer Issues: If the logical system is part of a transport layer, it may not have been transported correctly.
  Authorization Issues: The user may not have the necessary authorizations to access the logical system.
  Network Issues: There may be network connectivity issues preventing the RFC connection.
  
  Solution:
  
  
  Check Logical System Configuration:
  
  Go to transaction SALE (or SPRO -> SAP Reference IMG -> Integration with Other SAP Components -> Logical System -> Define Logical System).
  Ensure that the logical system you are trying to connect to is defined and active.
  
  
  
  Verify RFC Destination:
  
  Use transaction SM59 to check the RFC destination settings.
  Ensure that the destination is correctly configured and points to the correct logical system.
  Test the connection from SM59 to ensure it is working.
  
  
  
  Check Transport Layer:
  
  If the logical system is part of a transport layer, ensure that it has been properly transported and is available in the target system.
  
  
  
  Review Authorizations:
  
  Ensure that the user has the necessary authorizations to access the logical system. Check roles and profiles assigned to the user.
  
  
  
  Network Connectivity:
  
  Check for any network issues that may be preventing the connection. Ensure that firewalls or network settings are not blocking the RFC connection.
  
  
  
  Check for System Updates:
  
  Ensure that both systems (the one initiating the RFC call and the one being called) are updated and compatible with each other.
